Application filed Eovember The prime object of the presentinvention isto provide an article of manufacture of novel structure, and adapted toserve an entirely new purpose. 7

The new purpose is that of providing a yieldingly floatingly mountedplatform or resiliently elevated and more or less oscillatory floorboard for persons who have hitherto suffered great fatigue from beingcompelled to stand on or walk about a confined area for long periods, asharbors, housewives at the ironing board, attendants at automaticmachines, and so forth. The novel structure involved is one whichentirely eliminates fixed pivotal points of support for the floor board,while providing at the same time an exceedingly simple, inexpensive andsatisfactory construction, and one which, having a very few parts, is soconstructed that these parts may be readily assembled to set up the newstanding board anywhere, or readily disassembled and compactly bundledto facilitate transportation and storage,

The inv ntion will be more clearly understood from the followingdescription, when taken in connection with the accompanying drawing,showing one of the many possible embodiments of the invention as nowpreferred.

In this drawing:

Fig. l is a perspective view'of such embodiment; and

Fig. 2 is a side elevation, partially in section. 7

From amere inspection of this drawing, and before a detailed descriptionthereof is given, it will be instantly seen that an article ofmanufacture is provided which is quite different in structure andinpurpose from athletic spring-boards, exercisers, and the like, in whichconsiderable latitude of movement is permitted between the resilientmembers of the understructure and the platform or equivalent Referringnow to the details of such drawing, the platform of the presentinvention is indicated at 8, and constitutes an auxiliary floor board toact as the direct tread support of the standing person. By theexpression floor board, of course, is meant a floor structure of anysuitable kind; that is to say, not necessarily a single board asillustrated, or a board of the shape shown, since in the latterparticular it will, of course, be understood that the outlines anddimensions of the floor structure will be varied according 22, 1922.Serial 1T0. 692,555.

to the intended usefor the new article,

Tnus, he member 8 would desirably be shaped in outline like a fractionof an annu. is, if de ,red for use at a barbers chair.

resnient elements which form the essential part, of the structure, inthat they alone, and without any auxiliary pivoting or bracing means,serve to support the floor board resiliently floatingly, comprise aplurality of axially compressible vertical columns of any suitablematerial or construction, as columns of rubber. Preferably, however,such resilient elements comprise, as her shown, substantially vertical,cylindri'cally coiled compression or expansile springs, as indicated at4:. The parts last mentioned will be hereinafter referred to as theinterposed resilient members.

These interposed resilient members are received at their upper ends insuitable recesses on the underside of the floor board, and at theirbottom ends in suitable recesses on the upper faces of separate blocksor foot boards 5. These blocks, like the floor board, are convenientlyconstruct-ed of wood. In the aresent construction, where the interposecresilient members are the cylindrical coiled springs 4:, each recess inthe floor board is cylindrical as indicated at 6, as is the recess ineach block as indicated at 7; an important feature of the inventionbeing that the depths and diameters of such recesses are so arranged,relative to the resilient characteristics of the springs and thetendency of the latter to increase the diameters of their top and bottomterminal coils on compression axially, as from the weight of the floorboard or of the latter plus the weight of a person thereon, that thecoils mentioned expand sufficiently within the recesses to grip the samefrictionally and tightly and thus serve to lock the whole articletogether when assembled as shown in the drawing.

The ease of assembly and disassembly of the nine simple partsconstituting the embodiment of the new article of manufacture justdescribed, and the compact space within which the parts may be packedfor transportation and storage after disassembly is so apparent from thedrawing that it is not necessary to dilate thereon.

It will, of course, be appreciated that various changes may be made inthe general form and arrangement of the parts described Withoutdeparting from the invention, and

cise details set forth, but consider ourselves at liberty to make suchchanges and alterations as fairly fall within the spirit and scope ofthe appended claim.

We claim:

its a new article of manufacture, a' standing board adapted to besupported on a floor comprising a board of an area large enough topermit a person standing thereon to walk in various directions thereonand formed with recesses on its under face at the corners thereof, aplurality of foot members, each formed with a recess in its upper face,said foot members being adapted to rest loosely on a floor, and springseach having its ends in a recess 01: the board and in a recess of a footmember the diameter of the recesses being such with respect to the sizeor the springs that the springs will engage the walls of the recessesand be securely held therein by the expansion of the springs, the

recesses being of such a diameter and depth with respect to the springsthat thelatter are held in the recesses by friction, said springs andfoot members serving as legs for the board adapted to be readily appliedto and removed from the board and When removed to be disconnected fromeach other.
